I've always thought an M16A4 clone, complete with ACOG, could be a fun toy. Bushmaster was selling them for awhile, 20-inch barrels with 1:7 twist and forearm rails, as the USMC Rifle, but they don't appear to be doing so now. KAC's SR-15 looks very similar, though IIRC it may have an 18-in barrel.
